Apparatus for obtaining nitrogen from the atmosphere.



D. FRANK SL 0. FINGKI-J. APPARATUS PGR OBTAININ@ NITROGEN FROM THEATMQSPHERB, APPLIGATELUM@ Film) PHIL-10, 1912.

07,423., Y .Pwtentdmommwls lus from the outside, one may advantageouslymake the copper incandescentl by sending an eleetric Currentihrough it.

The apparatus c is preferably made in pairs so that always one of *,lieapparatuses can be cut out for the purpose of reducing the oxid 'ofcopper formed which reduction is carried out by introdu-:ing Water gasor methylic alcohol at d, While the other apparatus is working.

The pipe. h c' leads from the apparatus e to the furnace c whichcontains the mixture of bases and metals. The'fases evolved in Linefurnace 7c can be collected by means of suitable devices such as Athosewell known appliances employed in working blast Jfurnaces. After thenitrogen -lias been aiosorbed, the mass is removed from the furnace 7sand is ready for use.

Havingl now fully described our said in vention, what We claim anddesire to secure by Letters Patent, is:

l. An apparatus 'from the atmosphere, comprising a e0inpress'd airreceptacle, an air tight receptacle, lined with copper, copper baieplates inounl'ed in the air tight of copper supported in the receptacle,a pipe Communicating with the boiler and Adie or obtaininff nisroffenreceptacle, a body Lerares@ receptacle, a valve iu the pipe,.a sleaininici'. pipe communicating with the aforesaid pipe, a valve in the steampipe, a, furnace, a pipe communicating with the furnace and thereceptacle and a valve in the latter pipe.

2. An apparaius for obtaining nitrogen from die atmosphere comprising acompressed air receptacle, a pair of air tight receptacles, eachreceptacle having a plurality of copper baille plates mounted therein, abody of copper supported in each receptacle, a pipe communicationleading from he boiler, branch pipes extending from said lat ter pipeand-communicating with the"'pair of receptacles, a valve in each branch,a

steam inlet pipe communicating with the pipe leading, from the boiler, avalve in said steam pipe7 a furnace, a pipe leading 'from the furnace,branch pipes leading from the latter pipe and communicating with thereceptacles, and a Valve in each of the latter branch pipes,

ln testimony whereof Wehave hereunto setA our hands in piesence of twoWitnesses.
